Eight letters are arranged in a circle. Swipe your finger across adjacent letters to spell words, then lift your finger to submit. In Classic Mode you have 2 minutes to find as many words as possible. In Endless Mode the timer resets with every word you find, and used letters are replaced with fresh ones.

Golden words are words with 6 or more letters found in Classic Mode. They earn a 2× score multiplier and trigger a special particle effect.

3-letter = 1 pt, 4-letter = 2 pts, 5-letter = 5 pts, 6-letter = 8 pts, 7-letter = 10 pts, 8 letters = 15 pts. In Classic Mode, golden words (6+ letters) earn a 2× multiplier on top.
